DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

FIG. 1 is a schematic diagram illustrating a cloud server system according to an embodiment of the invention. In the present embodiment, a cloud server system 100 includes a cloud server 110 and an electronic apparatus 120. The cloud server 110 is, for example, a data center or other similar server apparatuses and server systems installed on a cloud network. The cloud server 110 includes a storage unit 112, a communication unit 114 and a processing unit 116.

The electronic apparatus 120 is, for example, a cell phone, a smart phone, a personal computer (PC), a notebook PC, a netbook PC, a tablet PC, a television, a game console, a portable apparatus, or a portable multimedia player. The electronic apparatus 120 includes a storage unit 122, a communication unit 124, a processing unit 126 and a random access memory 128.

Each of the storing units 112 and 122 may be, for example, a memory, a hard disk or other devices capable of storing data for recording a plurality of program codes or modules. Each of the communication units 114 and 124 may be configured to process Radio Frequency (RF) signals of cellular communication technology such as Global System for Mobile (GSM) system, 3GPP LTE, Code Division Multiple Access (CDMA), WCDMA, High Speed Packet Access (HSPA), World Interoperability for Microwave Access (WiMAX) and so on. In addition, the communication units 114 and 124 may further process RF signals of Wireless Local Area Network (WLAN) communication technology.

Each of the communication units 114 and 124 may include a transmitter circuit, a receiver circuit, an analog-to-digital (A/D) converter, a digital-to-analog (D/A) converter, a low noise amplifier (LNA), a mixer, a filter, a matching circuit, a transmission line, a power amplifier (PA), one or more antenna units and a local storage media component (but the invention is not limited thereto), so as to provide communication functions for the cloud server 110 and the electronic apparatus 120 in FIG. 1.

The processing unit 116 of the cloud server 110 is coupled to the storage unit 112 and the communication unit 114. The processing unit 126 of the electronic apparatus 120 is coupled to the storage unit 122, the communication unit 124 and the random access memory 128. Each of the processing units 116 and 126 may be, for example, a processor for general purposes, a processor for special purposes, a conventional processor, a data signal processor, a plurality of microprocessors, one or more microprocessors, controllers, microcontrollers and Application Specific Integrated Circuit (ASIC) which are combined to a core of the digital signal processor, a Field Programmable Gate Array (FPGA), any other integrated circuits, a state machine, a processor based on Advanced RISC Machine (ARM) and similar products.

In the present embodiment, the processing unit 116 may access a plurality of modules stored in the storage unit 112, and the processing unit 126 may access a plurality of modules stored in the storage unit 122, so as to execute a cloud data management method proposed by the invention.

FIG. 2 is a flowchart illustrating the cloud data management method according to an embodiment of the invention. In the present embodiment, the method proposed by the present embodiment can be executed by the cloud server 110 and the electronic apparatus 120 in FIG. 1, and each step of the present embodiment is described in detail with reference to each element depicted in FIG. 1.

In step S210, the processing unit 126 of the electronic apparatus 120 executes an application launcher installed on the electronic apparatus 120 to send a connection establishing request RQ to the cloud server 110 installed with an application through the communication unit 124 of the electronic apparatus 120. In step S220, the processing unit 116 of the cloud server 110 may establish a connection with the electronic apparatus 120 according to the connection establishing request RQ. The application is, for example, a business application dedicated to manage business data, but the implementation of the invention is not limited thereto.

In an embodiment, when the connection establishing request RQ is received, the cloud server 110 may execute an identity authentication procedure for the electronic apparatus 120 to confirm whether the electronic apparatus 120 and the user thereof have the qualification for accessing information in the cloud server 110. The identity authentication procedure includes, for example, controlling the electronic apparatus 120 to display a login screen that is configured for the user of the electronic apparatus 120 to enter identity information such as an account name and a password. In other embodiments, if the application stored in the cloud server 110 is the business application dedicated to manage business data of one specific company, the account name of the user may be set as, for example, an employee number or an email account of the user in the specific company, but the implementation of the invention is not limited thereto.

After the electronic apparatus 120 passed the identity authentication procedure, the cloud server 110 may provide a private storage space dedicated to the user of the electronic apparatus 120 through the connection so that the electronic apparatus 120 may store/access data. Under this circumstance, the application may be, for example, installed on said private storage space. In other embodiments, after the electronic apparatus 120 passed the identity authentication procedure, the cloud server 110 may also provide a public storage space that can be shared by multiple employees of the specific company so that the employees may store/access data. Under this circumstance, the application may be, for example, installed on said public storage space so that each of the employees may gain access to the application and related data thereof.

In step S230, the processing unit 116 of the cloud server 110 implements a management policy for the application, and sends a finishing command CMD to the electronic apparatus 120 through the communication unit 114 of the cloud server 110 after implementing the management policy. The finishing command CMD is, for example, a command used to inform the electronic apparatus 120 that the management policy is already implemented for the application by the cloud server 110 and the electronic apparatus 120 is allowed to load the application into the electronic apparatus 120 from the cloud server 110, but the implementation of the invention is not limited thereto.

In an embodiment, the management policy includes a virus scan operation, a data integrity check operation and an audit operation. In other embodiments, when the cloud server 110 is additionally stored with running state data related to the application such as a data file, a registry, cache data, a configuration file and a profile, the processing unit 116 of the cloud server 110 may also implement the management policy for said running state data. Further, the cloud server 110 may send the finishing command to the electronic apparatus 120 after implementing the management policy for the application and the related running state data thereof.

From another perspective, because the cloud server 110 is capable of implementing the management policy for the application, it can be ensured that the data related to the application and accessed by electronic apparatus 120 is safe and integral.

In other embodiments, in the case where the cloud server 110 is capable of allowing multiple users to access the same application and related data thereof, a manager of the cloud server 110 is able to allow the users to access the same application and related data thereof simply by managing the data stored on the cloud server 110. As such, since the manager no longer needs to deploy the application and the related data individually onto the electronic apparatuses of the users, a convenience in management may be improved accordingly.

In step S240, the processing unit 126 of the electronic apparatus 120 is capable of receiving the finishing command CMD from the cloud server 110 through the connection and loading the application into a sandbox in the random access memory 126 through the application launcher in response to the finishing command CMD.

In an embodiment, when the electronic apparatus 120 receives the finishing command CMD from the cloud server 110 through the connection, the processing unit 126 of the electronic apparatus 120 may further load the running state data (in which the management policy is already implemented by the cloud server 110) related to the application into the sandbox in the electronic apparatus 120 through the application launcher.

In another embodiment, the sandbox is, for example, a simulated environment (e.g., a block that is divided from random access memory 128 and dedicated to the application) established in the electronic apparatus 120 by the processing unit 126. After being loaded into the sandbox, the application cannot access or influence other programs or hardware outside the sandbox. Meanwhile, the application cannot be accessed or influenced by the programs or hardware outside the sandbox either.

That is to say, for the user, the application (e.g., the business applications implementing the company policy) and the data will no longer be mixed with personal application and data owned by the user. Furthermore, the personal data of the user will no longer be collected by the business applications implementing the company policy.

In addition, because the application is installed on the cloud server 110 but not installed the electronic apparatus 120, the user only needs to install the application launcher with special design on the electronic apparatus 120 in order to load the application installed on the cloud server 110 through the application launcher. In other words, the user no longer needs to install various business applications related to work on the electronic apparatus 120. Accordingly, the method proposed by the present embodiment of the invention is also capable of improving a user experience at the same time.

On the other hand, the company will no longer need to concern about the confidential business data being leaked when the user loses the electronic apparatus 120, or being stolen by malicious software in the electronic apparatus 120.

In an embodiment, the application is, for example, a responsive application, which adaptively adjusts a graphical user interface layout (GUI layout) presented by the electronic apparatus 120 in response to a screen size, a resolution and an operating system of the electronic apparatus 120. For instance, the application running in the sandbox may request the sandbox for the screen size, the resolution and the operating system of the electronic apparatus 120, so that the sandbox may then request the electronic apparatus 120 for aforesaid information.

Also, the application may further adjust the GUI layout presented by the electronic apparatus 120 in response to a conventional interface configuration of the operating system used by the electronic apparatus 120. For instance, in the case where a “Confirm” button is disposed at the left side of a “Cancel” button by the operating system of the electronic apparatus 120, the application may accordingly adjust the “Confirm” button generated during operation to be disposed at the left side of the “Cancel” button. On the other hand, in the case where the “Confirm” button is disposed at the right side of the “Cancel” button by the operating system of the electronic apparatus 120, the application may also accordingly adjust the “Confirm” button generated during operation to be disposed at the right side of the “Cancel” button, but the implementation of the invention is not limited thereto.

In an embodiment, when the electronic apparatus 120 requests to open a file or a registry related to the application, the processing unit 116 of the cloud server 110 may further implement the management policy for the file or the registry and then open the file or the registry thereafter. On the other hand, when the electronic apparatus 120 requests to close the file or the registry related to the application, the processing unit 116 of the cloud server 110 may further close the file or the registry and then implement the management policy for the file or the registry thereafter.

In brief, when the electronic apparatus 120 requests to open/close the file (or the registry), mechanisms implemented by the processing unit 116 of the cloud server 110 are “implementing the management policy before opening the file” and “closing the file before implementing the management policy.” Accordingly, not only the safety and data integrity of the file accessed by electronic apparatus 120 can be ensured, safety and data integrity of the file stored by the cloud server 110 after the electronic apparatus 120 completes use of the file may also be ensured.

Referring to FIG. 3, FIG. 3 is a schematic diagram illustrating an interaction between the cloud server and the electronic apparatus according to an embodiment of the invention. In the present embodiment, the electronic apparatus 120 may load an application 310 installed on the cloud server 110 into a sandbox SB of the electronic apparatus 120 through an application launcher 312 according to foregoing teachings (corresponding to an arrow 315). Subsequently, when the electronic apparatus 120 intends to open the file or the registry on the cloud server 110 (corresponding to an arrow 320), the processing unit 116 of the cloud server 110 may implement the mechanism of “implementing the management policy before opening the file” according to a procedure 322. Accordingly, the electronic apparatus 120 may then open the file (which is represented by a running state 325). Thereafter, when the electronic apparatus 120 intends to close the file or the registry on the cloud server 110 (corresponding to an arrow 330), the processing unit 116 of the cloud server 110 may implement the mechanism of “closing the file before implementing the management policy” according to a procedure 332.

Referring to FIG. 4A, FIG. 4A illustrates a schematic diagram for capturing a state snapshot according to an embodiment of the invention. In the present embodiment, when the application 310 is running in the sandbox, the processing unit 126 of the electronic apparatus 120 may further capture a state snapshot of current running state data related to the application 310, and redirect the state snapshot to the cloud server 110 through the communication unit 124 of the electronic apparatus 120. The current running state data includes, for example, the data file, the registry, the cache data, the configuration file and the profile generated while running the application 310, but the invention is not limited thereto.

In an embodiment, when the application 310 is initially running in the sandbox, the state snapshot is a full copy of the current running state data. In other embodiments, when the application 310 is not initially running in the sandbox, the state snapshot records a state difference between the current running state data and a previous state snapshot.

In brief, when the application 310 is not initially running in the sandbox, the processing unit 126 of the electronic apparatus 120 may simply captures the state difference only, so as to reduce a data quantity required by the redirection. However, when the application 310 is initially running in the sandbox, because the previous state snapshot does not exist, the processing unit 126 of the electronic apparatus 120 must redirect the full copy of the current running state data to the cloud server 110.

Referring to FIG. 4B, FIG. 4B illustrates a schematic diagram for capturing a last state snapshot according to an embodiment of the invention. In the present embodiment, when the application 310 is suspended, the processing unit 126 of the electronic apparatus 120 may capture and send a last state snapshot to the cloud server 110, and remove all data related to the application 310 from the random access memory 128 of the electronic apparatus 120.

Referring to FIG. 5, FIG. 5 illustrates a schematic diagram for resuming application and migrating application according to an embodiment of the invention. In the present embodiment, when the electronic apparatus 120 loads the application 310 into the sandbox through the application launcher again (corresponding to an arrow 515), the processing unit 116 of the cloud server 110 may further implement the management policy for a state snapshot 510 and then send the state snapshot 510 to the electronic apparatus 120 (corresponding to an arrow 520). The state snapshot 510 may be, for example, the last state snapshot as mentioned above, or may be the state snapshot previously redirected to the cloud server 110 at any time-point. As such, the processing unit 126 of the electronic apparatus 120 may then obtain the state snapshot 510 from the cloud server 110. When the state snapshot 510 is the last state snapshot, the electronic apparatus 120 may resume to a running state 525 before running the application 310. Thereafter, the electronic apparatus 120 may perform various interactive mechanisms, such as opening/closing the file and redirecting other state snapshots (represented by an arrow 530), with the cloud server 110, and related description regarding the same is not repeated hereinafter.

In other embodiments, assuming that the electronic apparatus 120 is previously suspended due to system failure, when the electronic apparatus 120 loads the application 310 into the sandbox through the application launcher again (corresponding to an arrow 515), the electronic apparatus 120 may also execute aforesaid mechanisms in order to recover back to the running state before running the application 310.

In the present embodiment, if the cloud server 110 determines that a user of an electronic apparatus 540 is identical to the user of the electronic apparatus 120 through the identity authentication procedure, the electronic apparatus 540 may also perform various aforementioned interactions with the cloud server 110 through an application launcher 542, so as to achieve the effectiveness of migrating the running state of the application 310 to the electronic apparatus 540.

In summary, the cloud data management method proposed by the embodiments of the invention is capable of allowing the electronic apparatus to load the application installed on the cloud server into the sandbox in the electronic apparatus through the application launcher in order to prevent the application (e.g., the business applications implementing the company policy) and the data thereof from being mixed with the private application and the data thereof, such that the user experience may be improved and the risk of leaking the confidential business data may also be reduced.

Further, because the cloud server is capable of implementing a specific management policy for the application and the related data thereof, it can be ensured that application and the data thereof accessed by the electronic apparatus as well as the data redirected to the cloud server by the electronic apparatus are both safe and integral. In addition, by adopting the mechanism in which the electronic apparatus redirects the state snapshot to the cloud server, the mechanisms for resuming the application, recovering the application and migrating the application to another electronic apparatus may all be realized easily.
